Definitions
- the various aspects are related to translucent building elements, and more specifically their manufacture.
- Building elements are known, more specifically concrete elements, with multiple elongated, light-conducting elements which extend in the structural element between two opposite surfaces so that the ends of each light-guiding element debouch in one of the respective surfaces.
- Walls in buildings can be made with such translucent concrete elements, where the light-conducting elements debouch in one of the two opposite surfaces of the wall. Light can then travel from one side of the wall to the other through the light-conducting elements, creating a translucent effect where light shines through the wall.
- These known translucent concrete elements are manufactured by pouring concrete in a mould, and placing light-conducting elements in the mould, before or during pouring, so that after the concrete has hardened a concrete element results in which the light-conducting elements extend between two opposite surfaces of this element.
- EP 2 144 332 discloses a light conducting building element.
- the element comprises a first layer of concrete, a layer of isolating material comprising multiple sub-layers, in which light conducting fibres are provided between the isolating sub-layers, and a second layer of concrete.
- the light conducting fibres extend through the concrete layers.
- Two building elements may be manufactured in one batch, by providing three layers of isolating material comprising sub-layers with light conducting fibres are provided in between. Subsequently or in parallel, concrete is poured between the layers of isolating material and at outer sides of the layers of isolating material. Finally, the concrete layers within the block thus constituted are cut parallel to the orientation of the layers to arrive at a concrete-isolation-concrete building element.
- US 2011 185660 A1 discloses the preamble of claim 1.
- claim 1 provides a method for the manufacture of an insulating core element for a translucent building element.
- This method allows a core element to be manufactured which can in turn be used to manufacture an insulated, translucent building element, such as a concrete element, or an insulated translucent building wall, such as a concrete wall, where the light-conducting elements which pass through the layer of insulating foam can be used to guide light through an insulated, translucent building element or an insulated, translucent building wall.
- An advantageous way with which such a core element manufactured using this method according to the invention can be used to manufacture a translucent building element or an insulated translucent building wall is described in detail below.
- the insulating foam is preferably a type of hard foam. Particularly good results are possible with polyurethane foam (PU foam), a 2-component hard foam with a watertight, closed cell structure.
- the method of manufacturing of a core element according to the invention is in itself particularly advantageous in view of the manner in which the separation panels are obtained through which the elongated, light-conducting elements protrude.
- These separation panels make it possible to form a particularly effective insulating foam from liquid components in the space between these separation panels, through which space the elongated, light-conducting elements extend. Allowing the separation panels to arise, in accordance with the invention, from the stacking of rows of mutually connected, elongated, light-conducting elements means it is not necessary, for example, to pass the light-conducting elements one by one through two panels with holes in order to create the separation panels.
- the provision of two separation panels comprises providing a first set of auxiliary walls that are parallel to one another; which auxiliary walls are provided with the grid of multiple elongated light-conducting element which extend parallel to each other perpendicular to the auxiliary walls and which extend through the auxiliary walls such that between the auxiliary walls of the first pair of auxiliary walls an auxiliary space is provided and providing a second set of auxiliary walls that are parallel to one another, which auxiliary walls are provided with the grid of multiple elongated light-conducting element which extend parallel to each other perpendicular to the auxiliary walls and which extend through the auxiliary walls such that between the auxiliary walls of the second pair of auxiliary walls an auxiliary space is provided.
- the method further comprises providing a formwork such that the first auxiliary space and the second auxiliary space are closed at least along at these panels of the compartments, providing a foam-forming substance in the first auxiliary space between the separation panels which substance is to form a mono-block of insulating foam; and providing a foam-forming substance in the second auxiliary space between the separation panels which substance is to form a mono-block of insulating foam.
- An advantage of this embodiment is that robust separation panels are obtained, which are resistant to the pressure and temperature which occur in foam formation of larger amounts of foam-forming substance.
- the provision of two separation panels, respectively the auxiliary panels comprises the provision of multiple stacked rows of elongated light-conductive elements, where each row comprises multiple elongated light-conducting elements positioned next to each other and which are mutually connected by means of at least two elongated connecting elements extending substantially parallel to each other and substantially transverse to the longitudinal direction of the light-conducting elements at a distance from the ends of the light-conducting elements, whereby the connecting elements of two rows stacked on top of each other are in sealing contact with each other, so that the connection elements of the stacked rows form at least two separation panels, respectively auxiliary panels, which extend substantially perpendicularly to the longitudinal direction of the light-conducting elements, and define an intermediate space, respectively compartment, between them.
- providing multiple stacked rows of elongated light-conducting elements comprises:
- a new row of elongated, light-conducting elements is repeatedly formed on a preceding row after the forming of the preceding row, whereby, when connecting the new row of elongated, light-conducting elements, the connecting elements of the new row are brought into sealing contact with the connection elements of the preceding row, so obtaining the multiple stacked rows of elongated light-conducting elements with the separation panels.
- providing multiple stacked rows of elongated light-conducting elements comprises:
- providing a multiple of stacked rows of elongated light-conducting elements comprises:
- a stack of multiple rows of light-conducting elements is formed by folding the mat at the end of the row after laying a row, in order to form a next row on the previously laid row, all using a single mat. This means that when folding the mat, the connecting elements of the mat which connect the light-conducting elements with each other are folded over at the same time, and the part of it after the fold is placed in sealing contact with the part in front of the fold, in order to obtain multiple stacked rows of elongated light-conducting elements with the separation panels.
- the step of providing a light-conducting mat in an advantageous embodiment comprises:
- each connecting element comprises two elongated sections which are arranged on both sides of the light-conducting elements.
- the elongated elements are enclosed between the two sections.
- at least one of the sections is provided with an adhesive layer which, in connecting the elongated light-conducting elements, is brought in contact with the elongated light-conducting elements and the other section. In this way, after the manufacture of the mat and the subsequent handling of the mat, the light-conducting elements maintain their position relative to the adjacent light-conducting elements.
- At least one of the two connecting elements which are brought into sealing contact with each other when manufacturing multiple stacked rows of elongated light-conducting elements is provided with an adhesive layer which is brought into contact with the other connecting element.
- the connecting elements of a row to be formed are provided with an upward-facing adhesive layer, on which adhesive layer the light-conducting elements which are to form the row are arranged in a row.
- the adhesive layer connects the light-conducting elements to connecting elements.
- the connecting elements of the next row of light-conducting elements to be formed can be positioned on the light-conducting elements of the preceding row, so that these, in the spaces between adjacent light-conducting elements, are in contact with the upward-facing adhesive layer of the connection elements of the preceding row. If these connecting elements of the next row to be formed are also provided with an upward-facing adhesive layer, the light-conducting elements of the row to be formed can be arranged on the adhesive layer, just as with the preceding row. By repeatedly placing a new row of light-conducting elements on a previous row, the multiple stacked rows of light-conducting elements can be manufactured in an advantageous manner.
- the light-conducting capacity of the light-conducting elements it is also important that these have such a bending stiffness that the light-conducting elements can remain standing independently and generally vertical over the distance between their ends and the nearby separation panel, with the respective end facing upwards. The importance thereof is explained in more detail below in the description of the method of manufacturing a translucent building element according to the invention.
- the elongated connecting elements are flexible, more specifically in the direction transverse to the plane in which the light-conducting elements of each respective row extend.
- the connecting elements are able to adapt to the course of the connecting element they are brought into contact with during the forming of the stack of a multiple of rows of light-conducting elements.
- the elongated connecting elements are compressible. This makes it possible to partially form connecting elements around the individual light-conducting elements that are connected, in order to thus make possible a sealing contact between the connecting elements and the corresponding mutually connected light-conducting elements.
- the advantage of compressible auxiliary panels and/or separation panels, whether or not composed of elongated connecting elements is that the structure is resistant to different pressures that occur upon expansion and/or curing of the foam-forming material and hardening of other materials that are used in combination with the core element, such as concrete.
- a further aspect also relates to an insulating core element for a translucent building element, preferably but not exclusively obtained from a method according to the invention as described above.
- the insulating core element comprises two separation panels which are parallel to each other, a mono-block of insulating foam extending between separation panels and a grid of multiple elongated light-conducting elements which extend parallel to each other, substantially perpendicular to a first plane of the mono-block and perpendicular to the separation panels and a second plane of the mono-block, where the second plane is located opposite the first plane, and where the light-conducting elements extend outside the mono-block.

After arranging a number of light-conducting elements on the lower sections 7a, 9a, the lower sections and light-conducting elements 5 arranged on them are moved in the direction of arrow A, so that a subsequent part of the lower section is drawn from the rollers 11, upon which a number of light-conducting elements 5 is arranged as described above.
- the upper sections 7b, 9b are thus glued onto the lower sections 7a, 9a and the light-conducting elements 5 arranged thereon by adhesive layers k, and form, together with the lower sections 7a, 9a, two connecting elements 7, 9 which extend parallel to each other and perpendicularly to the longitudinal direction L of the light-conducting elements 5.
- both the upper and the lower sections 7a, 7b, 9a, 9b are provided with an adhesive layer k
- only the upper sections 7a, 9a, or only the lower sections 7b, 9b may be provided with an adhesive layer k. Since the sections are made of compressible material, the sections form themselves at the light-conducting elements 5 around these elements 5.
- the sections are, for example, elements available in the market such as compriband, compressible strips or flexible foam material with an adhesive layer.
- a row R of mutually connected, elongated, light-conducting elements 5 is manufactured.
- the connecting elements 7 and 9 are situated at a distance b from the ends of the light-conducting elements 5.
- the row R manufactured according to Figure 1 of mutually connected, light-conducting elements 5 is formed into a light-conducting mat M1 by cutting off a part of manufactured row R.
- the first mat M1 is positioned on a stacking table T.
- the centre-to-centre distance c between two light-conducting elements 5 of two rows stacked on top of each other Rn, Rn-1 depends on the thickness d of sections 7a, 7b, 9a, 9b of the connecting elements.
- a thickness d of a section of 3.25 mm results in a centre-to-centre distance c of 6.5 mm between two light-conducting elements of two rows stacked on top of each other.
- the connecting elements 7, 9 form two separation panels 15, 17 which extend substantially perpendicularly to the longitudinal direction L of the light-conducting elements 5 and define between them an intermediate space 19.
- a light-conducting mat M is repetitively formed by taking a part of the manufactured row R, and the thus formed mat Mn is placed on a previously formed mat Mn + 1 so as to obtain multiple stacked rows Rn light-conducting elements 5.
- a subsequent row of mutually connected light-conducting elements 5 is formed on the mutually connected light-conducting elements 5 manufactured earlier, in the manner shown in Figure 1 .
- the upper sections 7b, 9b can be left out. This has the advantage of simplifying the process, more specifically by reducing the number of operations.
- the vertical centre-to-centre distance c between light-conducting elements situated one above the other is smaller.
- Figures 4 to 9 show an embodiment of the method according to the invention for the manufacture of an insulating core element.
- This method comprises providing a multiple of stacked rows of light-conducting elements, such as the multiple of stacked rows Rn of light-conducting elements shown in Figure 3 .
- the method shown in Figures 1 to 3 can thus precede the process shown in Figures 4 to 9 , or be part of it.
- a formwork 21 is shown, where, as shown in Figure 5 , the stack S of multiple stacked rows of light-conducting elements 5 is placed. Sealing strips 23 are applied to the formwork, which contribute to good sealing between the ends of the connecting elements 7, 9 and the walls 21a, 21b of the formwork 21.
- the formwork 21 closes the intermediate space between two separation panels 15, 17 along three edges of the separation panels 15, 17 with three formwork walls 21a, 21b, 21c.
- premixed reactive components 23 are poured into the closed intermediate space 19 between separation panels 15, 17, where these components react with each other to produce an insulating foam.
- the open top of the intermediate space 19 containing the foam-forming reactive components 23 is closed by means of a fourth formwork wall 21d, so that the intermediate space 19 is closed along four edges of the separation panels 15, 17.
- holes 25 in the fourth wall 21d allow excess foam 27 and air to leave the closed intermediate space 19 during the formation of the insulating foam.
- the insulating core element 29 has a core layer 31 of insulating foam material, and the core layer 31 extends between the separation panels 15 and 17.
- the light-conducting elements 5 protrude on two sides of the core element 29 out of the separation panels 15, 17, and pass through the separation panels 15, 17 and the core layer 31.

- the formwork 21 is designed such that it creates a compartment 33 on both sides of the insulating foam-filled intermediate space 19 of the insulating core element, wherein the formwork walls 21a, 21b, 21c, and 21d form the side walls of the compartment 33 and the respective separation panel 15, 17 forms a base wall from which the elongated light-conducting elements 5 protrude.
- one of the compartments 33 has its open side facing upwards.
- One of the ends of the light-conducting elements 5 protrude from the base of the compartment, formed by one of the separation panels 15, 17.

- the surface 39 from which the ends of the light-conducting elements 5 slightly protrude is smoothed by concrete grinding, such that a smooth surface 41 is created on which the ends of the light-conducting elements 5 debouch, as shown in Figure 14 .
- This building element 43 is, more specifically, an insulated, translucent concrete element with a sandwich structure.
- the sandwich construction comprises two outer shells 45, 47 or outer layers of concrete separated by a core layer 31 of insulating foam material. As shown in Figure 14 , the separation panels 15, 17 are visible in the building element 43.
- the light-conducting elements 5 extend through the concrete outer shells 45, 47 and core layer 31. The opposite ends of each light-conducting element 5 debouch in two opposite surfaces 41a, 41b of the concrete element 43.
- Light can enter the light-conducting elements 5 on one side of the concrete element 43, and is led by the light-conducting elements 5 through the outer shells 45, 47 of concrete and the core layer 31 of insulating foam to the opposite side of the building element 43, where it exits the ends of the light-conducting elements 5.

- Figures 16 to 20 show an embodiment of the method according to the invention for manufacturing a translucent building wall.
- This method comprises providing multiple insulating core elements, such as multiple core elements 29 as shown in Figure 10 .

- Figures 16 to 18 show how, according to the method according to the invention for manufacturing a translucent building wall, multiple core elements 29a to 29f are positioned in a formwork 49.
- the insulating foam-filled intermediate spaces 19 of adjacent core elements 29, in other words the core layers 31, are placed against each other to form a core wall.
- the separation panels 15, 17 of the core elements 29 then together form separation panels of the core wall.
- core elements 29 are then glued to each other.
- the formwork 49 which extends along the edges of the separation panels 51 of the obtained core wall, forms on both side of the core wall a compartment 53.
- the walls 49a, 49b, 49c, 49d of the formwork 49 form side walls of the compartment 53, and the corresponding separation panel of the core wall forms a base panel from which the elongated light-conducting elements 5 protrude.
- Figure 18 thus shows one of the compartments with the open side facing upwards.
- the ends of the light-conducting elements 5 protrude from the base of the compartment, formed by one of the separation panels of the core wall.
- Figure 19 shows a lance 35 pouring a concrete mixture 37 in the compartment 53 of which the open side is facing upwards up to, as shown in Figure 20 , below the ends of the light-conducting elements 5 protruding through the respective separation panel.
- the surface 55 from which the ends of the light-conducting elements slightly protrude is smoothed by concrete grinding, so that a smooth surface is created from which the ends of the light-conducting elements 5 debouch.
- This building wall is, more specifically, an insulated, translucent concrete wall with a sandwich construction.
- the sandwich construction is similar to that of the translucent building element 43 shown in Figure 15 .
- the sandwich construction comprises two outer shells or outer layers of concrete separated by a core wall of insulating foam material.
- the light-conducting elements extend through the concrete outer shells and core wall. The opposite ends of each light-conducting element debouch in the two opposite surfaces of the concrete wall.
- Light can enter the light-conducting elements on one side of the concrete wall, and is led by the light-conducting elements through the outer shells of concrete and the core wall of insulating foam to the opposite side of the concrete wall, where it exits the ends of the light-conducting elements.
- a building wall more specifically a concrete sandwich wall, with a translucent effect is obtained.
- An alternative way to obtain the translucent building wall is to stack multiple translucent building elements of Figure 15 .

- first compartment 19a Between the auxiliary panels of the first pair of auxiliary panels there is a first compartment 19a, and between the auxiliary panels of the second pair of auxiliary panels there is a second compartment 19b.
- the compartments are closed on three sides by means of a formwork 21.
- a foam-forming substance 23 is poured into the first compartment 19a, and a foam-forming substance 23 is poured into the second compartment 19b.
- foam-forming substances are the same.
- the foam-forming substances include, in one embodiment, two or more reactive components, which react with each other under the formation of foam when they are brought together.
- Such a foam could be polyurethane foam, where the reactive components are a di-isocyanate or similar, and for instance a polyol.
- the foam is expanded polystyrene.
- the foam-forming substance comprises only one substance, and foam-forming takes place under the influence of an external stimulus, preferably steam.
- the di-isocyanate could be seen as a foam-forming material in that context, and the polyols (or other substances with sufficient OH groups) seen as an external stimulus.
- foam-forming substances can also be used in the other embodiments discussed above.
- Figure 22 shows the arrangement as shown in Figure 21 , after formation of foam, and preferably after curing of the foam.
- the first pair of auxiliary panels with the foam between them forms a first separation panel 15, and the second pair of auxiliary panels with the foam between them thus forms a second separation panel 17.
- a foam-forming substance 23 is poured in intermediate space 19, which is located between the first separation panel 15 and the second separation panel 17. This may be the same foam-forming substance as used for the separation panels, but it may also be a different foam-forming substance.

- the height of the layer of concrete is preferably substantially the same as the length b shown in Figure 10 .
- the height of the formwork 21 is significantly higher than the length b, but the height of the layer of concrete is preferably substantially the same as length b.

In addition, this can ensure that the ends of the light-conducting elements 5 coincide with the opposite surfaces 41a, 41b. If the layer of concrete as shown in Figure 24 is slightly thicker than length b ( Figure 10 ), then the concrete surface 41b is polished to a thickness that is the same or less than length b.
- the layer of concrete as shown in Figure 27 is slightly thinner or thicker than length b, then the light-conducting elements 5 are shortened by means of polishing and/or other measures to the height of the concrete, and/or the concrete at the surface 41a is polished until the ends of the light-conducting elements 5 coincide with the opposite surfaces 41a, 41b.
